Question

If maths isn't used in real life other than adding and subtracting then why is it needed? :/

Answer 1

Math is also used in real life every day by scientists, engineers, computer professionals, architects.  Did you know that a baker, yes, the guy/gal who makes bread in a bakery, needs to master math?  Same goes for a professional chef to calculate portions, a pastry chef needs to calculate the amount of flour and other ingredients according to the size of the cake.  Anyone who gets a pay cheque wants to verify if the amount is correct.  We can go on and on.

Answer 2

Mostly I agree with you although you have to recognize math's significance. Without people who can do math, we would not have many of the things we take for granted. We wouldn't have cars, highways, or plane travel -- math is required to build and design such basic and complex things. Tall buildings? Architecture is heavily math based. Anything electricity based or phone and computer based also requires many math calculations to function.

Math is very functional. Most of us use it without even thinking about it. Ever go shopping? How much do you determine how much of a product to buy? You probably take into count how many people will be eating, as well as how much each person will have.

How do you know if bigger is better? Lots of products come in "value sizes",  usually with a higher price tag, yet with a bigger volume and saving a few dollars or so. Simple math helps you determine whether or not you are truly are getting more for your money.

Are "combo meal deals"  really a better option at resturants? Why buy a so called combo meal for $4.99 when you can head to McDonald's and get a sandwhich, fries, and drink for only $1 a piece?

Math is used all the time.The reasoning and logic behind it helps us avoid getting ripped off.
